TA31101NS16ARDQ from GR, in a SOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 E.rect passive Expander rectification smoothing capacitor terminal. Connects to a 2.2 uF capacitor to ground; the internal ~6.8 ohm R_RECT plus emitter resistance sets the expander rectifier time constant (attack/recovery).
2 INE.rect input Expander rectifier input (E.RECT_IN). Input impedance of the rectification input is approximately 9.5 kOhm. Typically AC-coupled from EXP_IN via 10 uF.
3 INE.ΔG input Expander gain-cell input (E.ΔG_IN). Input impedance of the gain-cell input is approximately 15 kOhm. Typically AC-coupled from EXP_IN via 10 uF.
4 GND power_in Ground reference (0 V) for the device.
5 Vref output Internal reference voltage output (REG-derived reference used by both channels). Typically bypassed with 10 uF to ground. Input reference level is -20 dBV typical.
6 E.NF passive Expander op-amp negative feedback / NF node. Sets expander cut-off frequency with an external capacitor and the internal 20 kOhm R_NF.
7 Outexp output Expander output (EXT_OUT / EXP_OUT). Drives external load via 10 uF AC-coupling capacitor; maximum output voltage ~800 mVrms into RL=10 kOhm.
8 E.cp passive Expander phase-compensation terminal (E-Cp). External 150 pF capacitor to Outexp provides phase compensation to prevent oscillation in the expander feedback loop.
9 C.cp passive Compressor phase-compensation terminal (C-Cp). External 150 pF capacitor to Outcomp provides phase compensation to prevent oscillation in the compressor feedback loop.
10 Outcomp output Compressor output (COMP_OUT). Drives external load via 10 uF AC-coupling capacitor.
11 INcomp input Compressor input (COMP_IN). Feeds the compressor op-amp summing node through internal R_COMP_IN ~20 kOhm.
12 C.NF passive Compressor op-amp negative feedback / NF node. External capacitor C10 sets compressor cut-off frequency together with internal 20 kOhm R_NF: fC = 1/(2π·C10·R_NF).
13 VCC power_in Positive supply voltage. Operating range 1.8 V to 9 V (recommended 3 V), absolute maximum 10 V. Typical quiescent current 2.7 mA at Vcc=3V.
14 INC.ΔG input Compressor gain-cell input (C.ΔG_IN). Input impedance of the gain-cell input is approximately 15 kOhm. Typically AC-coupled from COMP_IN via 10 uF.
15 INC.rect input Compressor rectifier input (C.RECT_IN). Input impedance of the rectification input is approximately 9.5 kOhm. Typically AC-coupled from COMP_IN via 10 uF.
16 C.rect passive Compressor rectification smoothing capacitor terminal. Connects to a 2.2 uF capacitor to ground; the internal ~6.8 ohm R_RECT plus emitter resistance sets the compressor rectifier time constant (attack/recovery).
